2.1. Analysis Groups

This is a Phase 1, open-label clinical trial of a single 4 g oral dose of zoliflodacin after an overnight fast. Eight healthy subjects who consent to participate in the trial and meet the eligibility criteria will be enrolled into a single cohort. Stratification will not be used in this study. All subjects will be analyzed in a single analysis group and no comparisons will be performed.

2.2. Dose Administration Eligible subjects will receive a single 4 g dose (2 sachets of 2 g of zoliflodacin reconstituted on the same day and administered in a total of ) orally after an overnight fast. The dose will be administered in a standardized cup. After the of zoliflodacin is administered, an additional will be added to the same cup and consumed by the subject to chase the initial dose. Both doses will be completed within a total of 5 min. After dosing, subjects will continue to fast for an additional 4 h while water is allowed ad lib.

2.3. PK Sampling Schedule Blood (plasma) samples will be collected into K2EDTA tubes at the following time points: On Day 1 at 30 min before dosing, and 0.5 h (±5 min), 1 h (±5 min), 2 h (±5 min), 3 h (±10 min), 4 h (±10 min), 6 h (±10 min), 8 h (±15 min), and 12 h (±15 min) after dosing; on Day 2 at 24 h (± 2 h) and 36 h (± 2 h) after dosing; on Day 3 at 48 h (±2 h) after dosing; and on Day 4 at 72 h (±2 h) after dosing, or early termination.

2.4. Analytical Methods Plasma concentrations of zoliflodacin will be determined using a validated HPLC-MS/MS method. The analysis will be performed by KCAS Bioanalytical Services. Details are included in the assay validation. For details of sample collection, processing, storage, transportation, and bioanalysis, see the protocol, MOP, and assay validation documents.

2.5. Collection of Pharmacodynamic or Clinical Endpoints Not applicable.

3.1. Analysis Population and Handling of Missing Time Points All subjects who received the study drug and who have at least one measurable drug concentration post- dosing will be included in the PK analysis population. Additionally, there will be a PK analysis subset, which includes all subjects who completed the PK part of the trial without any protocol violations or deviations that would likely affect the PK results and who have evaluable plasma concentration data for zoliflodacin from which at least the Cmax and Tmax can be determined (peak concentration and at least one decreased concentration after the peak observed). Zoliflodacin concentrations will be listed and shown graphically as individual profiles for all subjects in the PK analysis population, but concentration summary statistics, mean PK profiles, and NCA will use the PK analysis subset only. All enrolled subjects excluded from the PK analysis population or the PK analysis subset will be described in the PK Report, including reason for exclusion. Collection of plasma samples outside of the protocol defined time window for the time point will not result in exclusion of the sample result from NCA. If a sample is collected more than 10 min outside of the protocol defined time window, the sample result will be excluded from calculation of summary statistics for the respective time point, as well as from plots of mean concentration. Values below the lower limit of quantification (LLOQ) will be referred to as below the quantification limit (BQL). BQL values that precede the first PK concentration above the LLOQ will be imputed as 0 for linear plots and for all calculations including NCA and summary statistics, but will be excluded from semi- logarithmic plots. All other BQL values will be treated as missing for all analyses. Missing pre-dose PK samples will have concentrations imputed as 0 for analysis. All other missing PK sample concentrations will not be imputed for the NCA. A geometric mean (GM) of concentrations will be treated as missing for sets of data points containing an imputed 0 value due to a BQL value.

3.2. Demographic and Baseline Characteristics Sex, race, age, weight, height, and body mass index (BMI) of subjects in the PK analysis population will be listed and summarized (PK Table 1, PK Listing 1).

3.3. Dosing and Pharmacokinetic Sampling Summary Subject dose administration times will be presented (PK Listing 2). Cases that potentially affect the analysis will be discussed. Protocol deviations related to dosing or PK sampling will be listed (PK Listing 3) and summarized in the PK Report text. Deviations to be included in the PK Report include: • Treatment administration deviations • Blood specimen not collected • Plasma specimen result not obtained • Specimen temperature excursion • Required specimen collected out of window • Subject vomiting within 24 h of dose

- 3 - PRIVILEGED AND CONFIDENTIAL COMMUNICATION The Emmes Corporation Version 1.0 Noncompartmental Pharmacokinetic Analysis Plan – DMID Protocol: 16-0118 03 April 2018 • Subject ingestion of prohibited food or within the prohibited window after dosing • Any other deviation determined by the PK analyst to be potentially affect PK Drug plasma concentrations will be listed by subject (PK Listing 4), with nominal and actual time associated with the sample indicated (nominal time is defined as the time in h since the start time of the dose). Both laboratory reported concentration values, and modified concentration values used for analysis (for instance, imputation of 0 for a BQL value at baseline) will be included, as separate columns, in the listing. Plasma drug concentrations will also be summarized (PK Table 2) and plotted. PK Figure 1 and PK Figure 2 will plot all individual subject plasma PK profiles, as linear and semi-logarithmic plots, respectively. Subject ID for each individual profile in these figures will be shown in a legend. GM plots of zoliflodacin PK profiles will be shown in PK Figure 3. Semi-log mean plots of zoliflodacin PK profiles will be shown in PK Figure 4.

3.4. Definition and Estimation of Individual NCA PK Parameters PK parameters will be estimated through a NCA using version 8.0 or later of Phoenix® WinNonlin® (Pharsight Corporation, Cary, NC). Actual post-dose time will be used for the estimation of PK parameters instead of nominal time. Individual PK parameter estimates will be listed (PK Listing 5). Phoenix® WinNonlin® NCA will use the following settings to compute parameters from plasma PK data: • Linear Up Log Down calculation method • Uniform weighting • Extravascular dose • Plasma Model Type • Lambda Z Acceptance Criteria o Rsq_adjusted ≥ 0.80 o Span ≥ 3.0 half-lives

o Includes ≥ 3 timepoints after Tmax

▪ In exceptional circumstances, the data at Te may be included in computation of Ke if deemed necessary and appropriate by the PK analyst. If data at Tmax is included in computation of Ke, the decision will be justified in the PK Report.

Cmax

Maximum plasma concentration (Cmax) is defined as the maximum observed drug concentration observed in plasma over all PK sample concentrations. It will be obtained from the Cmax parameter calculated by ® WinNonlin . If there is no measurable concentration in the subject’s PK profile, then Cmax will be missing for that subject. Cmax will be reported in units of ng/mL.

Tmax

Time of maximum plasma concentration (Tmax) is defined as the time at which the Cmax occurs. It will be ® obtained from the Tmax parameter calculated by WinNonlin . If there is no measurable Cmax in the subject’s PK profile, then Tmax will be missing for that subject. Tmax will be reported in units of h.

Clast

- 4 - PRIVILEGED AND CONFIDENTIAL COMMUNICATION The Emmes Corporation Version 1.0 Noncompartmental Pharmacokinetic Analysis Plan – DMID Protocol: 16-0118 03 April 2018

Last observed (quantifiable) plasma concentration (Clast), in units of ng/mL. Clast will not be included in tables or listings, but is referred to in the definitions of other PK parameters.

Tlast ® Time of Clast (Tlast) will be obtained from the Tlast parameter calculated by WinNonlin . If there is no measurable concentration in the subject’s PK profile, then Tlast will be missing for that subject. Tlast will be reported in units of h.

Ke

The terminal phase elimination rate constant (Ke) is defined as the first-order rate constant describing the rate of decrease of drug concentration in the terminal phase (defined as the terminal region of the PK curve where drug concentration follows first-order elimination kinetics). Ke will be computed as the slope of a terminal region consisting of ≥3 successive points in the plot of log-transformed concentration data versus time. Ke will be estimated using uniform weighting. Time points used in the estimation of Ke will be initially selected using the WinNonlin® automatic algorithm.

The set of points chosen must contain only timepoints after Tmax and satisfy the Lambda Z Acceptance Criteria described above. Otherwise, the elimination rate constant and all derived parameters (t1/2, AUC(0-∞), CL/F, Vz/F) will be treated as missing.

The range of concentrations used to estimate Ke for each profile will be inspected by the PK analyst, who may adjust the set of concentrations used to estimate Ke if deemed necessary, but manually selected ranges must satisfy the same acceptance criteria as those chosen automatically by the WinNonlin® algorithm. Drug concentrations used to calculate Ke will be indicated in Listing 4. This parameter will be obtained from the ® Lambda_z parameter calculated by WinNonlin . Ke will be reported in units of 1/h. t½

The apparent terminal elimination half-life (t½) is defined as the time required for the drug concentration to decrease by a factor of one-half in the terminal phase. t½ can be estimated as ln(2) / Ke. It will be obtained ® from the HL_Lambda_z parameter calculated by WinNonlin . t1/2 will be reported in units of h. AUC

AUC(0-last) is defined as the area under the concentration-time curve from dosing (time 0) to the time of the last measured concentration. AUC(0-last) will be estimated using the Linear Up Log Down calculation method and obtained from the AUClast parameter calculated by WinNonlin®.

AUC(0-t) (partial AUC) is defined as the area under the concentration-time curve from dosing (time 0) to time t. AUC(0-t) may be computed for one or more values of t, with specific values of t determined after observing the data. It may be determined that no partial AUCs are required for inclusion in the PK Report. Specific times (t) AUC(0-t) will be estimated using the Linear Up Log Down calculation method.

AUC(0-∞) is defined as the total area under the concentration-time curve from dosing (time 0) taken to the limit as the end time becomes arbitrarily large. AUC(0-∞) can be calculated by adding AUC(0-last) to an extrapolated value equal to the last measured concentration greater than the LLOQ divided by Ke:

Clast AUC(0−∞) = AUC(0−last) + . Ke ® AUC(0-inf) will be obtained from the AUCINF_obs parameter calculated by WinNonlin . If the amount extrapolated portion of AUC(0-∞) is >20%, the estimated AUC(0-∞) value will be flagged when listed in the report and will be excluded from statistical summaries of parameter estimates and downstream calculations.

- 5 - PRIVILEGED AND CONFIDENTIAL COMMUNICATION The Emmes Corporation Version 1.0 Noncompartmental Pharmacokinetic Analysis Plan – DMID Protocol: 16-0118 03 April 2018 All AUCs will be reported in units of h×ng/mL. CL/F

Apparent oral clearance (CL/F) can be computed as Dose/AUC(0-∞). It will be obtained from the Cl_F_obs ® parameter calculated by WinNonlin . If the amount extrapolated portion of AUC(0-∞) is >20%, the estimated CL/F value will be flagged when listed in the report and will be excluded from statistical summaries of parameter estimates and downstream calculations. Clearance will be reported in units of L/h.

Vz/F

Apparent volume of distribution during terminal phase (Vz/F) after non-intravenous administration can be ® calculated as (CL/F)/ Ke. It will be obtained from the Vz_obs parameter in WinNonlin . If the amount extrapolated portion of AUC(0-∞) is >20%, the estimated Vz/F value will be flagged when listed in the report and will be excluded from statistical summaries of parameter estimates and downstream calculations. Volume will be reported in units of L.

3.5. Descriptive Statistics Subject-specific PK parameter estimates will be listed (Listing 5). PK estimates will be summarized in PK Table 3. Summary statistics will include mean, standard deviation (SD), minimum, maximum, median, coefficient of variation as a percent (CV%), GM, and geometric standard deviation (GSD).

3.6. Reporting Conventions P-values ≥0.001 and ≤0.999 will be reported to 3 decimal places; p-values <0.001 will be reported as “<0.001” The mean, SD, and other statistics will be reported to 1 significant figure greater than the original data. The minimum and maximum will use the same number of significant figures as the original data. Percentages will be reported to the nearest whole number; values >0 but <1% will be presented as “<1”; values >99% but <100% will be reported as >99%. AUCs will be reported as whole numbers. t1/2, Tmax, CL, and Vz/F values will be reported to 1 decimal place. Ke will be reported to 3 decimal places. Cmax will be reported with the same number of significant digits as the measurement. Ratios, location shifts (defined as a difference in mean or median), and associated 95% confidence intervals will be reported to 1 decimal place. Listings of individual subject data include a Subject ID column. The subject identifiers assigned by site staff are replaced throughout this report with the SDTM variable USUBJID to protect the confidentiality of those who volunteered to participate in this protocol. USUBJID has been created as a composite of the 3-letter Electronic Data Capture (EDC) platform code followed by a numeric identifier assigned chronologically to enrolled subjects as well as screening failures across all sites and protocols in the EDC platform. Any data sharing activities will include the USUBJID and not the subject identifiers assigned at the site.

1. PREFACE The Statistical Analysis Plan (SAP) for “A Phase 1 Clinical Trial to Evaluate the Plasma Pharmacokinetics, Safety, and Tolerability of a Single Oral Dose of Zoliflodacin in Healthy Male and Female Subjects” (Division of Microbiology and Infectious Diseases (DMID) protocol 16-0118) describes and expands upon the statistical information presented in the protocol. This document describes all planned analyses and provides reasons and justifications for these analyses. It also includes sample tables, listings, and figures planned for the final analyses. Regarding the final analyses and Clinical Study Report (CSR), this SAP follows the International Conference on Harmonisation (ICH) of Technical Requirements for Registration of Pharmaceuticals for Human Use Guidelines, as indicated in Topic E3 (Structure and Content of Clinical Study Reports), and more generally is consistent with Topic E8 (General Considerations for Clinical Trials) and Topic E9 (Statistical Principles for Clinical Trials). The structure and content of the SAP provides sufficient detail to meet the requirements identified by the Food and Drug Administration (FDA) and ICH, while all work planned and reported for this SAP will follow internationally accepted guidelines published by the American Statistical Association and the Royal Statistical Society for statistical practice. This document contains five sections: (1) a review of the study design, (2) general statistical considerations, (3) comprehensive statistical analysis methods for efficacy and safety outcomes, (4) planned statistical analyses for pharmacokinetic (PK) endpoints, and (5) a list of proposed tables and figures. Any deviation from this SAP will be described and justified in the CSR, as appropriate. The reader of this SAP is encouraged to also review the study protocol and manual of operating procedures for details on conduct of the study and the operational aspects of clinical assessments.

- 1 - PRIVILEGED AND CONFIDENTIAL COMMUNICATION Statistical Analysis Plan - DMID Protocol: 16-0118 Version 1.0 03 April 2018 2. INTRODUCTION This Phase 1 trial is an open-label, non-randomized evaluation of the PK and safety profiles of a single 4-g oral dose of zoliflodacin [2 x 2 gram (g) sachets] in 8 healthy male or female subjects, aged 18-45 years.

2.1. Purpose of the Analyses A single oral dose of zoliflodacin has been shown to be effective against uncomplicated gonorrhea caused by N. gonorrhoeae strains susceptible or resistant to currently available therapies. These findings supported the ongoing clinical development of zoliflodacin as a potential new therapeutic option for uncomplicated gonorrhea. A recently completed Phase 2 clinical trial suggests that zoliflodacin doses in the range of 2 g to 3 g are therapeutic. In the current study, a 4-g dose of zoliflodacin, using a different formulation than in the prior PK studies, is given to 8 healthy subjects. The purpose of analyses is to characterize the PK characteristics and safety profile of a 4-g dose of this formulation of zoliflodacin.

3.1. Study Objectives Primary Objective: • To evaluate the plasma PK of zoliflodacin after administration of a single 4-g oral dose under fasting conditions Secondary Objective: • To evaluate the safety and tolerability of a single 4-g oral dose of zoliflodacin

3.2. Endpoints Primary Endpoints:

• Cmax, Tmax, area under the curve (AUC) until last measurable concentration (AUC(0-last)), and other PK parameters for zoliflodacin determined using plasma concentrations of zoliflodacin in blood samples collected on Day 1 [baseline (30 min before dosing) and 0.5 h, 1 h, 2 h, 3 h, 4 h, 6 h, 8 h, and 12 h after dosing], Day 2 [24 h and 36 h after dosing], Day 3 [48 h after dosing], and Day 4 [72 h after dosing], or early termination (ET), and measured using a validated high performance liquid chromatography tandem mass spectrometry (HPLC-MS/MS) method Secondary Endpoints: • The occurrence of treatment-emergent serious adverse events (SAEs) from administration of zoliflodacin on Day 1 to Final Visit (Day 8 ± 2), or ET • The occurrence of unsolicited treatment-emergent adverse events (AEs) from administration of zoliflodacin on Day 1 to Final Visit (Day 8 ± 2), or ET • The changes from baseline (up to 60 min before dosing) in vital signs (VS) following administration of zoliflodacin, as measured on Day 1 [1 h, 2 h, and 4 h after dosing], Days 2, 3, and 4 [24 h, 48 h, and 72 h, respectively, after dosing], and Final Visit (Day 8 ± 2), or ET • The changes from baseline (Day -1) in clinical laboratory values following administration of zoliflodacin, as measured on Day 4, or ET • The changes from baseline (up to 60 min before dosing) in electrocardiograph (ECG) parameters following administration of zoliflodacin, as measured on Day 1 [1 h, 2 h, and 4 h after dosing] and Day 4 [72 h after dosing], or ET

3.3. Study Definitions and Derived Variables The baseline value will be defined as the last value obtained prior to the dosing with zoliflodacin.

4.1. Overall Study Design and Plan The trial will be performed as an open-label, non-randomized, single-dose design in 8 healthy male or female subjects to evaluate the PK and safety profiles of the zoliflodacin formulation. Zoliflodacin is presented as granules for oral suspension, 50 % weight(wt)/wt, packaged in a single sachet. Each subject will receive a single 4g dose of zoliflodacin (2 sachets of 2 g of zoliflodacin reconstituted on the same day and administered in a total of ) orally after an overnight fast. After the of zoliflodacin is administered, an additional should be added to the same cup and consumed by the subject to chase the initial dose. Ingestion of the content of both the initial volume and the wash should be completed within 5 min. All subjects will be dosed in the morning of Day 1 in a staggered fashion with a minimum of several minutes apart. There is no placebo used in this study. Subjects will participate in the study for approximately 4 weeks, including a 3-week screening period, a 4-day inpatient stay with dosing on Day 1, and a 1-week follow-up period after study product administration. The last follow-up visit is scheduled on Day 8. Safety oversight will be conducted by a Safety Monitoring Committee (SMC), which is an independent group of experts that monitors subject safety and advises DMID. The SMC will review safety data and advise on using the 4-g dose of zoliflodacin in a subsequent thorough QT study.

4.2. Discussion of Study Design, Including the Choice of Control Groups Zoliflodacin is a spiropyrimidinetrione antibacterial drug, which inhibits bacterial Deoxyribonucleic acid (DNA) synthesis by a novel mechanism. Zoliflodacin demonstrates in vitro activity against N. gonorrhoeae strains that are susceptible or resistant to current available therapies and in vivo efficacy, including in patients with uncomplicated gonorrhea.5,6 Regulatory guidance ICH/FDA E14 has emphasized the need to obtain robust data on the effect of new chemical entities on ECG parameters, focusing on cardiac repolarization as measured by the corrected QT interval (QTc).6 To obtain these data, the potential of a single therapeutic dose and a single supratherapeutic dose of the study drug to prolong cardiac repolarization is measured. Single zoliflodacin doses ranging from 200 mg to 4 g were generally safe and well tolerated in the Phase 1 and Phase 2 clinical trials conducted to date in healthy subjects and patients with uncomplicated gonorrhea.5,7,8 The current trial will further characterize the PK and safety profiles of the 4-g dose of a new zoliflodacin formulation. This dose could result in drug exposures that are multiples of the proposed 2-g therapeutic dose and meet the requirements for a supratherapeutic dose. Since the main objective is to characterize the PK of zoliflodacin, this study does not use a control group.

4.3. Selection of Study Population Only subjects who meet all of the inclusion and none of the exclusion criteria will be eligible for enrollment into this study. No exemptions are granted on Inclusion/Exclusion Criteria in DMID-sponsored studies. Eight healthy male and female subjects, aged 18-45 years inclusive, will be enrolled in a single cohort.

4.4.1. Treatments Administered Zoliflodacin is a spiropyrimidinetrione antibacterial agent, with a novel mode of action. It is a first-in-class oral gyrase inhibitor being developed for treatment of uncomplicated gonococcal infection, including cases caused by isolates with resistance to currently available treatments. A single oral dose of zoliflodacin has been shown to be effective against uncomplicated gonorrhea caused by N. gonorrhoeae strains susceptible or resistant to currently available therapies. These findings supported the ongoing clinical development of zoliflodacin as a potential new therapeutic option for uncomplicated gonorrhea.

4.4.2. Identity of Investigational Product(s) Zoliflodacin is presented as granules for oral suspension, 50 % wt/wt, packaged in a single sachet. Each sachet contains 2 g of spray-dried zoliflodacin, co-formulated with .

4.4.3. Method of Assigning Subjects to Treatment Groups (Randomization) This is a single arm trial. All subjects will receive a single 4 g oral dose of zoliflodacin.

4.4.4. Selection of Doses in the Study Single zoliflodacin doses ranging from 200 mg to 4 g were generally safe and well tolerated in the Phase 1 and Phase 2 clinical trials conducted to date in healthy subjects and patients with uncomplicated gonorrhea.1,2,3 The current trial will further characterize the PK and safety profiles of the 4-g dose of a new zoliflodacin formulation. This dose could result in drug exposures that are multiples of the proposed 2-g therapeutic dose and meet the requirements for a supratherapeutic dose according to the ICH/FDA E14 Guidance for thorough QTc studies.4

4.4.5. Selection and Timing of Dose for Each Subject Eligible subjects will receive a single 4-g dose (2 sachets of 2 g of zoliflodacin reconstituted on the same day and administered in a total of ) orally after an overnight fast. After the of zoliflodacin is administered, an additional will be added to the same cup and consumed by the subject to chase the initial dose. Ingestion of the content of both the initial volume and the should be completed within 5 min. After dosing, subjects will continue to fast for an additional 4 h while water is allowed ad lib. All subjects will receive zoliflodacin in the morning of Day 1 in a staggered fashion several minutes apart.

4.4.6. Blinding This is an open-label study, no blinding procedures are required.

4.4.7. Prior and Concomitant Therapy Concomitant medications include the following: prescription drugs, birth control hormonal preparations, non- prescription medication, herbs, vitamins, nutritional supplements, and illicit and recreational substances. Any of these taken before or after dosing will be reported as Prior Medications or Concomitant Medications, respectively.

- 8 - PRIVILEGED AND CONFIDENTIAL COMMUNICATION Statistical Analysis Plan - DMID Protocol: 16-0118 Version 1.0 03 April 2018 Prior prescription medication information will be recorded at Screening Visit and, except for hormonal contraceptives, should not be taken for 30 days before dosing or during the study period. Zoliflodacin should not be co-administered in subjects using strong (i.e., avasimibe, carbamazepine, phenytoin, rifampin, and St. John's wort) or moderate (i.e. efavirenz, bosentan, etravirine, modafinil, and nafcillin) inducers of CYP3A4. These drugs should not be taken for 30 days before dosing and during the study period. A vaccine should not be received within 30 days before dosing or before the end of the trial, except for licensed influenza vaccine during the flu season, which may be administered up to 7 days before or after dosing. Non-prescription medications, herbs, vitamins, and nutritional supplements should not be taken within 15 days before dosing. OTC medications taken for a brief period (<48 h) for the treatment of common symptoms (such as headache, indigestion, muscle pain) may be allowed as approved by the designated study clinician. Allowed medications include: oral contraceptives; H1 antihistamines; topical/ intranasal corticosteroids; nonsteroidal anti-inflammatory drugs (NSAIDS); licensed influenza vaccine during the flu season, 7 days before or after dosing. Blood/blood products (RBCs, WBCs, platelets, and plasma) should not be donated within 60 days of dosing or received before Final Visit. Following dosing, each new concomitant medication and changes to existing medications will be recorded. Subjects will be required not to utilize non-study medication during the trial except those deemed necessary by the Site PI or sub-investigator. Any drug (e.g., non-prescription medications, herbal supplements, vitamins, or prescription medications) or vaccine or blood/blood products used by the subject during the trial will be recorded in the subject’s source documents and on the appropriate electronic case report form (eCRF), and the PI or authorized study clinician (listed on FDA Form 1572) will note whether the use was medically indicated and immediately necessary. Any use of medications not authorized by the study PI or authorized clinician will be recorded as a deviation.

4.4.8. Treatment Compliance All subjects will receive a single 4 g dose of zoliflodacin administered in the clinic. Dates and times of administration will be recorded by site personnel. Complete information regarding any partial or interrupted dosing will be documented.

4.5. Efficacy and Safety Variables As this study is a Phase I clinical trial in healthy adult subjects, there will be no assessment of drug efficacy. Safety endpoints are briefly listed below. For a detailed schedule of activities, refer to Appendix A of the protocol. For a complete list of primary and secondary objectives and outcomes, refer to Section 3 of the SAP. Safety will be assessed by the timing, frequency, relatedness to study drug, and severity of: 1. Treatment-emergent SAEs occurring from dosing through Final Visit (Day 8 ± 2), or ET 2. Clinical laboratory AEs occurring from dosing through Final Visit (Day 8 ± 2), or ET 3. Non-serious, unsolicited treatment-emergent AEs occurring from dosing through Final Visit (Day 8 ± 2), or ET. Details of the study safety parameters can be found in the protocol.

- 9 - PRIVILEGED AND CONFIDENTIAL COMMUNICATION Statistical Analysis Plan - DMID Protocol: 16-0118 Version 1.0 03 April 2018 5. SAMPLE SIZE CONSIDERATIONS Since this is a pilot Phase 1, open-label trial with a single 4-g dose cohort of zoliflodacin, no formal sample size calculations based on testing a statistical hypothesis were constructed. Eight subjects will be enrolled, and it is planned to have seven evaluable subjects given zoliflodacin. This sample size will provide sufficient information to estimate exposure to the 4-g dose of zoliflodacin and to assess its safety.

- 10 - PRIVILEGED AND CONFIDENTIAL COMMUNICATION Statistical Analysis Plan - DMID Protocol: 16-0118 Version 1.0 03 April 2018 6. GENERAL STATISTICAL CONSIDERATIONS

6.1. General Principles Tabulations will be used extensively to summarize the data. Summary statistics for continuous data will include the mean, median, standard deviation, and range (minimum and maximum values). Summary statistics for discrete data will include counts and percentages, contingency tables, and associated confidence intervals (CIs). Denominators will be shown for all percentages (as N=X). When 95% CIs are given for a binary variable, Wilson Score CIs will be used. Parameters will be summarized overall and not by any subgroup. In general, all data will be listed, sorted by subject ID, and when appropriate, by visit number within subject. The total population size relevant to specific tables or to columns or rows within tables will be displayed. Listings of individual subject data include a Subject ID column. The subject identifiers assigned by site staff are replaced throughout this report with the SDTM variable USUBJID to protect the confidentiality of those who volunteered to participate in this protocol. USUBJID has been created as a composite of the 3-letter Electronic Data Capture (EDC) platform code followed by a numeric identifier assigned chronologically to enrolled subjects as well as screening failures across all sites and protocols in the EDC platform. Any data sharing activities will include the USUBJID and not the subject identifiers assigned at the site.

6.2. Timing of Analyses

The final analysis will be performed after database lock.

6.3. Analysis Populations

A tabular listing of all subjects, visits, and observations excluded from the analysis of PK data will be provided in the CSR (Listing 4).

6.3.1. Intention-to-Treat Analysis (ITT) Population Not applicable.

6.3.2. Full Analysis Population Not applicable.

6.3.3. Modified Intention-to-Treat (mITT) Population Not applicable.

6.3.4. Evaluable Population Not applicable.

6.3.5. Per Protocol Population Not applicable.

6.3.6. Safety Population All subjects who received the study drug will be included in the safety population and analyzed as treated.

- 11 - PRIVILEGED AND CONFIDENTIAL COMMUNICATION Statistical Analysis Plan - DMID Protocol: 16-0118 Version 1.0 03 April 2018 6.3.7. PK Population The PK analysis population will consist of all subjects who received zoliflodacin and have at least one quantifiable post-dosing drug concentration measured. The PK analysis subset will be based on the PK population, which includes all subjects who completed the PK part of the trial without any protocol violations that would likely affect the PK results and who have evaluable plasma concentration data for zoliflodacin from whom at least a subset of the designated PK parameters can be determined.

6.3.8. Immunogenicity Population Not applicable.

6.4. Covariates and Subgroups The protocol does not define any formal subgroup analyses, and the study is not adequately powered to perform subgroup analyses.

6.5. Missing Data All attempts will be made to collect all data per protocol. Clinical labs will not be collected for Day -1 if collected ≤7 days of dosing. Therefore, missing clinical laboratory results on Day -1 only will be imputed using last observation carried forward when results with 7 days prior to dosing are available. Missing clinical laboratory results on Day 4 or “Day 4 or ET” will not be imputed. Missing pre-dose PK samples will have concentrations imputed as BQL (below quantification limit). No other imputation will be performed for missing values. Outliers will not be excluded from the primary analyses. Outliers identified during the PK analysis will be discussed in the analysis report.

6.6. Interim Analyses and Data Monitoring There are no planned interim analyses for this study. An SMC will review all the safety data to Day 8 or ET in the study cohort. If any of the predefined objective criteria for halting the study, listed in Section 9.5.1 of the protocol, are met, a SMC ad hoc meeting will be held to review all available safety data (see Section 9.6.2 of the protocol for more details).

6.7. Multicenter Studies Not applicable. This is a single site study. 6.8. Multiple Comparisons/Multiplicity This is a small Phase 1 first-in-human study with multiple primary endpoints. The primary endpoints are descriptive rather than hypothesis tests, no adjustments for multiple testing are planned.

7.1. Disposition of Subjects Screened subjects who were ineligible for enrollment in the study will be summarized by inclusion and exclusion criteria in Table 7, and enrolled subjects who were ineligible for inclusion in the analysis populations will be presented by reason for subject exclusion in Table 6. Subject disposition will be summarized (Table 5), showing the number of subjects who screened, enrolled, dosed, completed sample collection, and completed follow-up. Subjects who terminated early from the study will be listed (Listing 1). Subjects who were excluded from the PK population, then PK analysis subset, or safety population will be listed, including reason for exclusion (Listing 4).

7.2. Protocol Deviations A summary of protocol deviations will be presented by the deviation category and reason in Table 2. This table will provide both the number of subjects and the number of deviations for each category. All subject-specific protocol deviations and non-subject-specific protocol deviations will be listed (Listing 2 and Listing 3, respectively).

- 13 - PRIVILEGED AND CONFIDENTIAL COMMUNICATION Statistical Analysis Plan - DMID Protocol: 16-0118 Version 1.0 03 April 2018 8. EFFICACY EVALUATION There are no efficacy endpoints for this trial

8.1. Primary Efficacy Analysis Not applicable.

8.2. Secondary Efficacy Analyses Not applicable.

8.3. Exploratory Efficacy Analyses Not applicable.

- 14 - PRIVILEGED AND CONFIDENTIAL COMMUNICATION Statistical Analysis Plan - DMID Protocol: 16-0118 Version 1.0 03 April 2018 9. SAFETY EVALUATION All safety analyses will be presented using the safety population. When calculating the incidence of AEs (i.e., on a per subject basis), each subject will be counted once and any repetitions of AEs within a subject will be ignored for events coded in the same category by the Medical Dictionary for Regulatory Activities (MedDRA); the denominator will be the total safety population size. Moreover, events thus summarized will be coded to the highest severity observed per toxicity tables (Table 3 and Table 4).

9.1. Demographic and Other Baseline Characteristics Sex, ethnicity, and race of all subjects will be summarized (Table 8). Ethnicity will be categorized as “Hispanic or Latino,” or “Not Hispanic or Latino,” or “Unknown/Not Reported.” In accordance with NIH reporting policy, subjects may self-designate as belonging to more than one race or may refuse to identify a race, the latter reflected in the eCRF as “No” to each racial option. Age (in years), height (in m), weight (in kg), and BMI (in kg/m2) will be summarized (Table 9). Individual subject listings will be presented for all demographic and baseline characteristics (Listing 5).

9.1.1. Prior and Concurrent Medical Conditions Medical history (MH) including all current illnesses and past pre-existing medical conditions will be MedDRA coded using MedDRA dictionary version 20.1 or higher. Summaries of subjects’ pre-existing medical conditions by MedDRA system organ class (SOC) will be presented (Table 10). Individual subject listings including medical history term, condition start and end day, SOC, and PT will be presented for all medical conditions (Listing 6). Surgeries, and the underlying illness indicating the surgery, were collected as separate medical history terms, and will be reported as separate rows in the listing.

9.1.2. Prior and Concomitant Medications All medications will be coded using the current version of the World Health Organization (WHO) Drug dictionary. The use of prior and concomitant medications taken during the study will be summarized by Anatomical Therapeutic Chemical (ATC) classification codes ATC 1 and ATC 2 (separately in Table 117 for prior medications and Table 118 for concomitant medications). Individual subject listings will be presented for all prior and concomitant medications (separately in Listing 18 for prior medications and Listing 19 for concomitant medications).

9.2. Measurements of Treatment Compliance All subjects were to receive a single 4 g dose of zoliflodacin administered in the clinic. The dates and times of administration are listed for each subject in Listing 7. Subjects unable to ingest the full amount of the initial of study drug suspension or who vomit within 24 h after dosing will be withdrawn from the study and replaced (See Section 5.3.3 and 5.3.4 of the protocol). Subjects who do not ingest the content of the second of study drug suspension will not be withdrawn from the study. Subjects who received any amount of the study drug but withdraw from the trial will be encouraged to continue follow-up (with subjects’ consent) for safety assessments and PK sample collection. Subjects receiving the full initial suspension and the full wash ( ) will be reported in Listing 7 as receiving “4 g” of the drug. Subjects receiving an incomplete dose will be reported in Listing 7 as receiving “<4 g” of the drug.

- 15 - PRIVILEGED AND CONFIDENTIAL COMMUNICATION Statistical Analysis Plan - DMID Protocol: 16-0118 Version 1.0 03 April 2018 9.3. Adverse Events When calculating the incidence of AEs within each category (i.e., on a per subject basis), each subject will only be counted once and any repetitions of AEs within a subject will be ignored; the denominator will be the total safety population size. When multiple AEs of different severities are observed for a subject within a category, the worst severity will be tabulated for calculations of incidence. All reported AEs will be included in the summaries and analyses.

9.3.1. Solicited Events and Symptoms There are no solicited symptoms or AEs in this trial.

9.3.2. Unsolicited Adverse Events The proportion of subjects reporting at least one unsolicited AE after dosing and prior to Day 8 or ET will be summarized by MedDRA SOC, higher level group term (HLGT), and preferred term (PT). A 95% Wilson Score CI will be presented for each MedDRA SOC, HLGT, and PT. Tables, figures, and listings of AEs will include clinical laboratory AEs and ECG AEs. AEs by subject will be presented in Listing 8. Additionally, moderate and severe non-serious AEs will be listed in Table 15. A brief overall summary of AEs will be given in Table 11. The following summaries for unsolicited AEs will be presented by MedDRA SOC, HLGT, and PT: • Frequency (number and percent of subjects with an AE of mild severity or greater, with 95% Wilson Score intervals) and number of AE, regardless of severity or relationship to study product (Table 12) • Frequency of AEs by severity and relationship to study product (Table 13); • Bar chart of frequency of related AEs by severity and MedDRA SOC (Figure 2). This figure describes the total number of occurrences of each AE, including multiple occurrences per subject. • Bar chart of incidence of serious and non-serious AEs by maximum severity and MedDRA SOC (Figure 1). This figure describes the number and percent of subjects with an AE.

9.4. Deaths, Serious Adverse Events and other Significant Adverse Events Individual data listings of deaths and Serious AEs (Table 14) will be provided. The listing will include: Subject ID, AE Description, Duration, Reason Reported as an SAE, Severity, Relationship to Treatment, Alternate Etiology if not Related, Outcome, MedDRA SOC, and MedDRA PT.

9.5. Pregnancies A female subject who participates in the trial and becomes pregnant will be asked to inform study personnel of a pregnancy occurring 30 days after the final study visit. A male subject who participates in the trial and whose female partner becomes pregnant 90 days after the final study visit will be asked to inform study personnel of the pregnancy. For all reported pregnancies, subjects will be asked to provide pregnancy outcome upon delivery or pregnancy termination to the clinical trial unit.

- 16 - PRIVILEGED AND CONFIDENTIAL COMMUNICATION Statistical Analysis Plan - DMID Protocol: 16-0118 Version 1.0 03 April 2018 An individual data listing of pregnancy reports will be provided in Listing 21, Listing 22, Listing 23, Listing 24, and Listing25 if a pregnancy occurs post dosing. A by-subject list of birth control methods can be found in Listing 20.

9.6. Clinical Laboratory Evaluations Toxicity grade criteria can be found in Table 3 and Table 4. Unscheduled or repeated follow-up tests for medical or safety reasons will be listed but excluded from tabular and graphical summaries. Clinical labs will not be collected for Day -1 if collected ≤7 days of dosing. In all cases, the most recent result in the database prior to dosing will be used as baseline. Missing clinical laboratory results on Day 4 or ET will not be imputed. If multiple Day -1 results exist for a subject, the latest result prior to dosing will be regarded as the baseline value. All clinical laboratory results (chemistry, hematology, and urinalysis) will be listed (Listing 9, Listing 10, and Listing 11). Other laboratory results (viral serology, pregnancy tests, and confirmation of menopause) will be listed separately (Listing 12). Toxicology results will be shown in Listing 13 and Breathalyzer results will be shown in Listing 14. Abnormal laboratory results will be listed in Table 16, Table 17, and Table 18. Chemistry laboratory results will be summarized by parameter and severity (including maximum severity post-baseline) regardless of relatedness (Table 19, Table 20, Table 21, Table 22, Table 23, Table 24, Table 25, Table 26, Table 27, Table 28, Table 29, Table 30 and Table 31) and additionally the frequency of related laboratory toxicities will be summarized by parameter and severity (including maximum severity post- baseline; Table 32, Table 33, Table 34, Table 35, Table 36, Table 37, Table 38, Table 39, Table 40, Table 41, Table 42, Table 43, and Table 44). Summary statistics will be reported by parameter and scheduled visit, including change from baseline (Table 45, Table 46, Table 47, Table 48, Table 49, Table 50, Table 51, Table 52, Table 53, Table 54, Table 55, Table 56, Table 57, Table 58, and Table 59). Individual line plots showing the laboratory result over time will be shown by chemistry parameter (Figure 3, Figure 4, Figure 5, Figure 6, Figure 7, Figure 8, Figure 9, Figure 10, Figure 11, Figure 12, Figure 13, Figure 14, Figure 15, Figure 16 and Figure 17). Subjects will not be labeled in the line plots, as the purpose of the figures is to give an overall trend of trajectory. The following chemistry parameters will be included in summaries of severity: sodium, potassium, bicarbonate, glucose, blood urea nitrogen, creatinine, protein, albumin, aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase, and bilirubin. The following chemistry parameters will be included in tables of summary statistics and in graphical plots: sodium, potassium, magnesium, chloride, bicarbonate, glucose, blood urea nitrogen, creatinine, protein, albumin, AST, ALT, alkaline phosphatase, bilirubin, and direct bilirubin. Hematology laboratory results will be summarized by parameter and severity (including maximum severity post-baseline) regardless of relatedness (Table 60, Table 61, Table 62, Table 63, Table 64, Table 65, Table 66, Table 67 and Table 68) and additionally the frequency of related laboratory toxicities will be summarized by parameter and severity (including maximum severity post-baseline; Table 69, Table 70, Table 71, Table 72, Table 73, Table 74, Table 75, Table 76 and Table 77). Summary statistics will be reported by parameter and scheduled visit, including change from baseline (Table 78, Table 79, Table 80, Table 81, Table 82, Table 83, Table 84, Table 85, Table 86, and Table 87). Individual line plots showing the laboratory result over time will be shown by hematology parameter (Figure 18, Figure 19, Figure 20, Figure 21, Figure 22, Figure 23, Figure 24, Figure 25, Figure 26, and Figure 27). Subjects will not be labeled in the line plots, as the purpose of the figures is to give an overall trend of trajectory. The following hematology parameters will be included in summaries of severity: hemoglobin, leukocytes, neutrophils, lymphocytes, monocytes, eosinophils, basophils, and platelets. The following hematology parameters will be included in tables of summary statistics

- 17 - PRIVILEGED AND CONFIDENTIAL COMMUNICATION Statistical Analysis Plan - DMID Protocol: 16-0118 Version 1.0 03 April 2018 and in graphical plots: hemoglobin, hematocrit, erythrocytes, leukocytes, neutrophils, lymphocytes, monocytes, eosinophils, basophils, and platelets. Urinalysis laboratory results will be summarized by parameter (protein, glucose, and hemoglobin) and severity (including maximum severity post-baseline) regardless of relatedness (Table 88, Table 89, Table 90, and Table 91) and additionally the frequency of related laboratory toxicities will be summarized by parameter and severity (including maximum severity post-baseline; Table 92, Table 93, Table 94, and Table 95). Because urinalysis parameters are not continuous (except for microscopy follow-up parameters in the event of abnormal urine), no tables of summary statistics or line plots will be produced for urinalysis results. If performed, results of microscopy follow-up tests to abnormal urine dipstick tests will be included in listings of urinalysis results. In tables of severity, maximum severity observed for the parameter after dosing will be summarized. Tables of maximum severity for “Any Parameter” will be included for chemistry, hematology, and urinalysis laboratory results. In these tables, the maximum severity across all laboratory results in the respective category is summarized by visit, and from maximum severity post baseline. Ordinarily, only the maximum severity event will be counted in the summary tables. For instance, if subject has a mild decrease and a moderate increase observed post-dose, they will be counted once as a moderate increase for maximum severity post-baseline. In the exceptional case that a subject has an increase and a decrease of equal maximum severity, they will be counted twice for maximum severity post baseline, once for an increase and once for a decrease.

9.7. Vital Signs and Physical Evaluations VS measurements include systolic blood pressure, diastolic blood pressure, pulse rate, respiratory rate, and oral temperature. VS will be assessed within 60 min of dosing (baseline), 1 h (±10 min), 2 h (±10 min), and 4 h (±10 min) after dosing, and at Day 2, Day 3, Day 4, and Day 8 or ET. VS will be tabulated by parameter, severity grading, and visit (Table 96, Table 97, Table 98, Table 99, Table 100, and Table 101) and listed (Listing 15). Additionally, descriptive statistics, including mean, standard deviation, median, minimum and maximum will be presented to summarize VS at baseline and post-dose and will also present change from baseline (Table 102, Table 103, Table 104, Table 105 and Table 106). For each vital sign, individual line plots showing the vital sign over time will be shown by parameter (Figure 28, Figure 29, Figure 30, Figure 31 and Figure 32). Subjects will not be labeled in the line plots, as the purpose of the figures is to give an overall trend of trajectory. In tables of severity, maximum severity observed for the parameter after dosing will be summarized. Tables of maximum severity for “Any Parameter” will be included for VS results. In these tables, the maximum severity across all VS is summarized by visit, and from maximum severity post baseline. Ordinarily, only the maximum severity event will be counted in the summary tables. For instance, if subject has a mild decrease and a moderate increase observed post-dose, they will be counted once as a moderate increase for maximum severity post-baseline. In the exceptional case that a subject has an increase and a decrease of equal maximum severity, they will be counted twice for maximum severity post baseline, once for an increase and once for a decrease. A complete physical examination (PE), except genital, rectal and breast exams, will be conducted at Screening and at Day 8 (± 2) or ET. This examination will assess general appearance, HEENT (head, eyes, ears, nose and throat), heart, lungs, abdomen, skin, musculoskeletal system, and lymph nodes, and include an abbreviated neurological exam. An abbreviated PE will be performed on Day -1 (unless a complete PE was performed < 7 days before dosing) and Day 4. An abbreviated PE differs from a complete PE in that the

- 18 - PRIVILEGED AND CONFIDENTIAL COMMUNICATION Statistical Analysis Plan - DMID Protocol: 16-0118 Version 1.0 03 April 2018 abdomen and neurological system are not evaluated. A symptom-directed PE will be performed before dosing on Day 1 and after dosing on Days 1, 2, and 3, to evaluate new symptoms or treatment-emergent AEs, respectively. Results of physical examinations, scheduled and unscheduled, will be presented in Listing 16.

9.8. Concomitant Medications All medications will be coded using the current version of the WHO Drug dictionary. The use of prior and concomitant medications taken during the study will be summarized by ATC 1 and ATC 2 (separately in Table 117 for prior medications and Table 118 for concomitant medications). Individual subject listings will be presented for all prior and concomitant medications (separately in Listing 18 for prior medications and Listing 19 for concomitant medications).

9.9. Other Safety Measures A 12-lead ECG and 10-sec rhythm strip will be obtained at Screening Visit and on Days -1, 1, and 4 (72 h ± 2 h post dose), or ET. On Day 1, a 12-lead ECG and 10-sec rhythm strip will be recorded within 1 h before dosing and 1 h (±10 min), 2 h (±10 min), and 4 h (±10 min) after dosing. ECG change in overall interpretation from baseline will be shown by study visit in Table 107. For PR interval and QT intervals with Fridericia correction (QTcF), ECG results will be tabulated by parameter, severity grading, and visit (Table 108 and Table 109). Summary statistics of ECG results, including change from baseline, will be reported by parameter (PR interval, QRS duration, QT interval, QTcF interval, RR interval, and ECG mean ventricular rate) in tabular form by study visit (Table 110, Table 111, Table 112, Table 113, Table 114, and Table 115) and will be shown graphically as line plots by visit (Figure 33, Figure 34, Figure 35, Figure 36, Figure 37, Figure 38, and Figure 39). Subjects will not be labeled in the line plots, as the purpose of the figures is to give an overall trend of trajectory. Line plots of change from baseline will be shown for QTcF intervals (Figure 37) but change from baseline will not be shown graphically for other ECG parameters. Frequency of QTcF prolongation (between 30 and <60 msec or ≥60 msec) will be given by post-dose visit (Table 116). Individual data listings of ECG results (interpretation, PR interval, QRS duration, QT interval, QTcF interval, RR interval, and ECG mean ventricular rate) will be presented (Listing 17).

Abnormalities of vital signs should be described as “increase X” or “decrease X” (X = heart rate, blood pressure, respiratory rate, temperature) if asymptomatic, transient and not associated with a systemic or organ-specific disorder, and coded by MedDRA within the System Organ Class (SOC) “Investigations.” These abnormalities should be graded per criteria in Appendix C of the protocol, but not considered in determining whether study stopping criteria have been met. On the other hand, abnormalities of vital signs that are either secondary to systemic or organ-specific clinical syndrome or primary disorders should be coded in the appropriate SOC (e.g., "cardiac disorders", respiratory disorders", "immunological disorders", etc.). These abnormalities should be considered in determining whether stopping criteria have been met.
